Description

本発明は、請求項１の前提部に記載された印刷技術的な機械にシートを供給する方法に関する。   The invention relates to a method for feeding sheets to a printing-technical machine as defined in the preamble of claim 1.

ドイツ連邦共和国特許第４４０７６３１号明細書には、枚葉印刷機において本刷りを始動する方法が記載されている。この方法では、本刷り回転数に達したあとではじめてパイルからのシートの個別化およびフィーダボードへのシートの搬送が行われることにより、始動時の損紙が回避される。これにより、主印刷回転数に枚葉印刷機を増速する間にシートが印刷されないことが保証されている。個別化の遅れた切換えにより、始動の始まりとシートの最初の印刷との間の時間長さが比較的大きくなっている。個別化された最初のシートは、高速でフィーダボードに搬送されるので、特に薄いシートでは、角隅部分が浮き上がり、これによりシート供給が損なわれる恐れがある。   German Patent No. 4,407,631 describes a method for starting a full print in a sheet-fed printing press. In this method, the sheet is not separated from the pile and the sheet is transported to the feeder board only after reaching the main printing rotation speed, thereby avoiding a paper loss at the time of starting. This ensures that no sheet is printed while the sheet-fed printing press is accelerated to the main printing speed. Due to the delayed individualization, the length of time between the start of the start and the first printing of the sheet is relatively large. Since the first individualized sheet is conveyed to the feeder board at a high speed, the corner portion is lifted particularly in a thin sheet, which may impair the sheet supply.

ドイツ連邦共和国特許第１９６３９１３４号明細書に基づく本刷りを始動する方法では、始動時の損紙は、枚葉印刷機を本刷り回転数に増速する前もしくは増速する間に、シート供給に切換えられることにより減じられる。シート供給に切換えるための時点は、最初のシートが本刷り回転数に達する時点でまたは達したあとではじめて機械の内側の所定の位置に達するように選択される。したがって枚葉印刷機を高い本刷り回転数で運転しようとする場合には、シート供給に切換えるための時点は、時間的に増速の開始後にある。フィーダボードに搬送される最初のシートは、比較的高い速度を有するので、角隅部分が浮き上がり、これによりシート供給が損なわれる恐れがある。   In the method of starting a main print according to the specification of German Patent No. 19639134, the waste paper at the start is supplied to the sheet supply before or during the speed increase of the sheet-fed printing press to the speed of the main printing. Reduced by being switched. The point in time for switching to sheet feeding is chosen to reach a predetermined position inside the machine only when or after the first sheet reaches the full speed. Therefore, when the sheet-fed printing press is to be operated at a high final printing speed, the point of time for switching to sheet feeding is after the start of speed increase in terms of time. Since the first sheet conveyed to the feeder board has a relatively high speed, the corner portion is lifted, which may impair the sheet supply.

ドイツ連邦共和国特許第４４０７６３１号明細書German Patent No. 4,407,631 ドイツ連邦共和国特許第１９６３９１３４号明細書German Patent No. 19639134

本発明の課題は、印刷技術的な機械にシートを供給する方法を改良して、シート供給の信頼性を改善し、基本速度から生産速度への増速時間を短縮することである。   The object of the present invention is to improve the method of feeding sheets to a printing-technical machine, to improve the reliability of sheet feeding, and to shorten the acceleration time from the basic speed to the production speed.

この課題を解決するために、本発明によれば、シートを、第１の駆動装置により、ずれ重なった形でフィーダボードに搬送し、別の駆動装置により、個別に順次フィーダボードから印刷技術的な機械の第１の加工ステーションに搬送し、その際、駆動装置を基本速度から出発して生産速度に増速する、印刷技術的な機械にシートを供給する方法であって、シートを、別の駆動装置が生産速度に達する前に、フィーダボードに搬送し、シートがフィーダボード上で搬送方向に所定の位置を占め、相互に所定の間隔を有すると、直ちに第１の駆動装置を停止し、次いで第１の加工ステーションが生産速度に達した後で、第１の駆動装置を生産速度に増速する。   In order to solve this problem, according to the present invention, the sheet is conveyed to the feeder board in the form of being shifted and overlapped by the first driving device, and individually printed sequentially from the feeder board by another driving device. A method for feeding a sheet to a printing-technical machine in which the sheet is transported to a first processing station of a simple machine, where the drive starts from the basic speed and increases to the production speed. Before the drive device reaches the production speed, it is conveyed to the feeder board, and when the sheet occupies a predetermined position in the conveyance direction on the feeder board and has a predetermined distance from each other, the first drive device is immediately stopped. Then, after the first processing station reaches the production speed, the first drive device is increased to the production speed.

好適には、シートがフィーダボードに搬送される速度を、シート厚さに応じて調節する。   Preferably, the speed at which the sheet is conveyed to the feeder board is adjusted according to the sheet thickness.

好適には、シートを、目下の増速速度よりも低い速度でフィーダボードに搬送する。   Preferably, the sheet is conveyed to the feeder board at a speed lower than the current speed increase speed.

好適には、駆動装置のために、個別に制御可能なモータを備える機械式に分離された伝動装置を用いる。   Preferably, mechanically separated transmissions with individually controllable motors are used for the drive.

好適には、駆動装置のために、連結可能な伝動装置を用い、伝動装置に、モータにより、トルクを伝達する。   Preferably, a connectable transmission device is used for the drive device, and torque is transmitted to the transmission device by a motor.

本発明によれば、シートは、生産速度に機械を増速する間に、好適には目下の増速速度よりも低い速度でずれ重なった形でフィーダボードに搬送される。機械の第１の加工ステーションが生産速度にあるときに、はじめてフィーダボードにシートを装着するための駆動装置が、その生産速度に増速される。それぞれ分離した、機械の加工ステーションのための駆動装置と、フィーダボード上で第１の加工ステーションに向かう搬送装置のための駆動装置とにより、シートを低い速度でずれ重なった形にすることができる。薄いシートの角隅部分が浮き上がる恐れはもはや存在しない。フィーダボード上の刺身状のシート形成が終了しているときに、加工プロセスは、機械が生産速度に達するとはじめて開始される。シートがフィーダボードに搬送される速度は、シート厚さに応じて調節することができる。シートがフィーダボード上で搬送方向に所定の位置を占めて、相互に所定の間隔を有するときに、刺身状のシート形成のための駆動装置は、一時的に停止することができる。   According to the present invention, the sheet is conveyed to the feeder board in a form that is preferably deviated and overlapped at a speed lower than the current speed increase speed while increasing the machine to the production speed. When the machine's first processing station is at production speed, the drive for loading the sheet on the feeder board for the first time is increased to that production speed. The separate drive units for the machine processing station and the drive unit for the conveying device on the feeder board towards the first processing station allow the sheets to be offset and stacked at a low speed. . There is no longer any fear that the corners of the thin sheet will rise. When the sashimi-like sheet formation on the feeder board is finished, the processing process is started only when the machine reaches the production speed. The speed at which the sheet is conveyed to the feeder board can be adjusted according to the sheet thickness. When the sheet occupies a predetermined position in the conveying direction on the feeder board and has a predetermined distance from each other, the driving device for forming a sashimi-like sheet can be temporarily stopped.

本発明は、シートがずれ重なった形で供給されるあらゆる印刷技術的な機械に適用可能である。本発明は、特に好適には、枚葉印刷機、折り機、打抜き機、折畳み箱接着機、シート加工機およびシート用の検査機器に適用可能である。   The present invention can be applied to any printing technology machine in which sheets are supplied in a stacked state. The present invention is particularly preferably applicable to sheet-fed printing machines, folding machines, punching machines, folding box bonding machines, sheet processing machines, and sheet inspection equipment.

以下に、本発明の実施の形態を、図示の態様に基づいて説明する。   Embodiments of the present invention will be described below based on the illustrated embodiments.

公知の枚葉印刷機は、それぞれ分離した、シートを個別化してフィーダに搬送するための駆動トレーンと、印刷ユニットを通ってシートを搬送するための駆動トレーンとを備える。図１の枚葉印刷機の概略図では、フィーダ１および２つの印刷ユニット２，３が図示されている。フィーダ１では、シート４がパイル５の上で準備された状態で保持されている。シート４は、吸着ヘッド４０により、パイル５の上面から個別化され、フィーダボード６に搬送される。シート４を前当て７に向かって前送りするために、とりわけ搬送ベルト８が働き、搬送ベルト８は、変向ローラ９，１０にわたって設けられている。シート４は、印刷開始前にフィーダボード６上でずれ重なった形に準備される。   A known sheet-fed printing press includes a drive train for separating and individually transporting sheets to a feeder and a drive train for transporting sheets through a printing unit. In the schematic view of the sheet-fed printing press of FIG. 1, a feeder 1 and two printing units 2 and 3 are shown. In the feeder 1, the sheet 4 is held in a state of being prepared on the pile 5. The sheet 4 is individualized from the upper surface of the pile 5 by the suction head 40 and conveyed to the feeder board 6. In order to advance the sheet 4 toward the front pad 7, the transport belt 8 works in particular, and the transport belt 8 is provided across the direction change rollers 9 and 10. The sheet 4 is prepared in a shape that is shifted and overlapped on the feeder board 6 before the start of printing.

印刷中、シート４は、スインググリッパ１１により、個別に順次前当て７から給紙ドラム１３のグリッパ１２に引き渡される。さらに進行すると、シート４は、給紙ドラム１３から圧胴２０のグリッパ１４，１５、渡しドラム２１のグリッパ１６，１７および圧胴２２のグリッパ１８，１９に引き渡される。ゴム胴２３，２４と圧胴２２，２２との間の印刷ギャップで、その都度シート４は、部分インキ像を有する印刷像を受取る。部分インキ像は、それぞれ版胴２５，２６上の刷版の着肉により形成される。版胴２５，２６は、ゴム胴２３，２４とインキ装置２７，２８のインキ着けローラとに回転接触している。   During printing, the sheet 4 is individually and sequentially delivered from the front pad 7 to the gripper 12 of the paper feed drum 13 by the swing gripper 11. As the sheet 4 further advances, the sheet 4 is delivered from the paper supply drum 13 to the grippers 14 and 15 of the impression cylinder 20, the grippers 16 and 17 of the transfer drum 21, and the grippers 18 and 19 of the impression cylinder 22. In each printing gap between the rubber cylinders 23, 24 and the impression cylinders 22, 22, the sheet 4 receives a printed image having a partial ink image. The partial ink images are formed by depositing the printing plates on the plate cylinders 25 and 26, respectively. The plate cylinders 25 and 26 are in rotational contact with the rubber cylinders 23 and 24 and the ink forming rollers of the ink devices 27 and 28.

印刷機を駆動するために、主駆動モータ２９が設けられており、主駆動モータ２９は、トルクを伝動装置３０に供給する。伝動装置３０は、ベルト駆動装置や歯車等の多数の伝送装置要素から成る。図示した二重線３１は、伝動装置要素の間もしくは伝動装置要素と結合されたローラ９，１０、ドラム１３，２１および胴２０，２２〜２６の間のトルク伝達もしくは力伝達を表す。ローラ９，１０、ドラム１３，２１および胴２０，２２〜２６は、矢印３２の方向に同期的に回転する。   In order to drive the printing press, a main drive motor 29 is provided, and the main drive motor 29 supplies torque to the transmission device 30. The transmission device 30 includes a number of transmission device elements such as a belt driving device and gears. The illustrated double line 31 represents torque transmission or force transmission between the transmission elements or between the rollers 9, 10, the drums 13, 21 and the cylinders 20, 22-26 coupled to the transmission elements. The rollers 9 and 10, the drums 13 and 21, and the drums 20 and 22 to 26 rotate synchronously in the direction of the arrow 32.

フィーダ１に設けられたシート搬送要素を駆動するために伝動装置３３が働き、伝動装置３３は、切換えクラッチ３４により、印刷ユニット２，３の駆動トレーンと連結可能である。伝動装置３３は、とりわけ吸着サッカ４０および搬送ベルト８を駆動するために働く。   A transmission device 33 works to drive the sheet conveying element provided in the feeder 1, and the transmission device 33 can be connected to the drive train of the printing units 2 and 3 by a switching clutch 34. The transmission device 33 serves in particular to drive the suction sucker 40 and the conveyor belt 8.

モータ２９および切換えクラッチ３４は、制御装置３５と接続されている。給紙ドラム１３の軸は、回転数センサ３６と接続されており、回転数センサ３６の信号出力は、制御装置３５に向かって導かれている。回転数センサ３６の出力信号は、給紙ドラム１３の周速もしくは枚葉印刷機の目下の印刷速度ｖを表す。   The motor 29 and the switching clutch 34 are connected to the control device 35. The shaft of the paper feed drum 13 is connected to a rotation speed sensor 36, and the signal output of the rotation speed sensor 36 is guided toward the control device 35. The output signal of the rotation speed sensor 36 represents the peripheral speed of the paper supply drum 13 or the current printing speed v of the sheet-fed printing press.

上述の枚葉印刷機を用いると、方法の第１の態様は、以下のように実施することができる：
印刷ジョブの処理前もしくは印刷中断後に枚葉印刷機を再始動するために、シート４は、ずれ重なった形でフィーダボード６に搬送される。クラッチ３４が解離された状態で、シート４を搬送するドラム１３，２１および胴２０，２２は、例えば３０００回転／分（給紙ドラム１３の回転／分）の空転速度ｖ１で回転する。図３に示すように、時点ｔ１で、枚葉印刷機を始動させるためのコマンドが与えられえ、次いで速度ｖが、時点ｔ２で例えば５０００回転／分の始動速度ｖ２に達するまで高められる。線３７は、印刷ユニット２，３を通ってシート４を搬送する際の速度変化を示す。フィーダ１の構成要素に関するシート４の速度変化は、二点鎖線３８で示す。時点ｔ３で、クラッチ３４が作動させられるので、伝動装置３３を介して、フィーダボードへのシート４の搬送が始まる。伝動装置３０，３３の固い連結により、フィーダボード６のシート装着時の速度は、シート４を搬送するドラム１３，２１もしくは胴２０，２２の速度の変化に追従する。時点ｔ４で、直線状の速度変化で印刷ユニット２，３の増速が始まる。時点ｔ５で、最初のシート４が前当７に当接するとき、フィーダボード６は完全にシート装着されているので、クラッチ３４は、再び解離され、フィーダ内１のシート搬送は停止される。フィーダボード６のシート装着時の最高速度ｖ３は、最初のシート４が角隅部分で浮き上がらずに前当て７に到着する程度に小さい。 With the above described sheet-fed printing press, the first aspect of the method can be implemented as follows:
In order to restart the sheet-fed printing press before processing the print job or after printing is interrupted, the sheet 4 is conveyed to the feeder board 6 in a form of being overlaid. In a state in which the clutch 34 is disengaged, the drums 13 and 21 and the cylinders 20 and 22 that convey the sheet 4 rotate at an idling speed v 1 of, for example, 3000 rotations / minute (rotation / minute of the paper supply drum 13). As shown in FIG. 3, at time t 1 a command can be given to start the sheet-fed press, and then the speed v is increased until reaching a starting speed v 2 of, for example, 5000 revolutions / minute at time t 2. It is done. A line 37 indicates a change in speed when the sheet 4 is conveyed through the printing units 2 and 3. The speed change of the sheet 4 with respect to the components of the feeder 1 is indicated by a two-dot chain line 38. Since the clutch 34 is actuated at the time t 3 , the conveyance of the sheet 4 to the feeder board is started via the transmission device 33. Due to the rigid connection of the transmission devices 30 and 33, the speed when the feeder board 6 is mounted follows the change in the speed of the drums 13 and 21 or the cylinders 20 and 22 that convey the sheet 4. Once t 4, the speed increasing printing units 2 and 3 begins with a linear velocity change. Once t 5, when the first sheet 4 abuts prior to those 7, since the feeder board 6 is fully seat mounted, the clutch 34 is again dissociated, the sheet conveyance of the feeder 1 is stopped. Maximum velocity v of the sheet when mounting the feeder board 6 3 is smaller to the extent that the first sheet 4 arrives at the front lays 7 without float in the corner portion.

後続の経過において、枚葉印刷機は、フィーダ１を停止状態にして、生産速度ｖ４に増速される。時点ｔ６でドラム１３，２１および胴２０，２２が生産速度ｖ４で回転するときに、待機時間ｔＷ１＝ｔ６−ｔ５の経過後、クラッチ３４の作動により、フィーダ１は、再び運転させられる。時点ｔ６からシート４は個別に順次スインググリッパ１１により前当て７から受け取られ、第１の印刷ユニット２に供給される。そのためにスインググリッパ１１にラチェットが接続される。ラチェットの開放時には、スインググリッパ１１によるシート搬送は防止されている。フィーダ１におけるシート搬送は、印刷ユニット２，３におけるシート搬送と同一の速度ｖ４で進行する。 In the subsequent process, the sheet-fed printing press is brought up to the production speed v 4 with the feeder 1 stopped. When the drum 13, 21 and cylinder 20, 22 at time t 6 is rotated at a production rate v 4, after the lapse of the waiting time t W1 = t 6 -t 5, the operation of the clutch 34, the feeder 1 is operated again Be made. From time t 6 , the sheets 4 are individually and sequentially received from the front pad 7 by the swing gripper 11 and supplied to the first printing unit 2. For this purpose, a ratchet is connected to the swing gripper 11. When the ratchet is opened, sheet conveyance by the swing gripper 11 is prevented. The sheet conveyance in the feeder 1 proceeds at the same speed v 4 as the sheet conveyance in the printing units 2 and 3.

図４には、方法の第２の態様を示している。図３における態様とは異なり、この態様では、フィーダボード６の完全シート装着後のフィーダ１の待機時間ｔｗ２もしくは停止時間ｔｗ２は、短縮されている。クラッチ３４は、時点ｔ７で中間回転数ｖ５＜ｖ４の場合に作動させられる。時点ｔ７から、シート４は、第１の印刷ユニット２に供給される。中間回転数ｖ５から生産回転数ｖ４へ増速する間にシート４は既に印刷される。時点ｔ６から、通常の本刷りが行われる。 FIG. 4 shows a second aspect of the method. Unlike embodiment in FIG. 3, in this embodiment, the standby time t w2 or stop time t w2 of the feeder 1 after complete sheet mounting of the feeder board 6 is shortened. The clutch 34 is operated when the intermediate rotational speed v 5 <v 4 at time t 7 . From time t 7 , the sheet 4 is supplied to the first printing unit 2. Sheet 4 during the accelerated from the intermediate rotational speed v 5 to produce rotational speed v 4 is already printed. From the time t 6, is usually of this printing is done.

図２に示す態様では、枚葉印刷機は、フィーダ１用の別個の駆動モータ３９を備える。したがって伝動装置３０，３３の間に機械式の駆動結合部は存在しない。モータ３９は、モータ２９と同様に、制御装置３５により制御される。このような駆動アッセンブリにより、印刷ユニット２，３とフィーダ１とは、相互に独立した速度プロフィールで運転することができ、これは図５に詳しく示している。始動速度ｖ２から生産速度ｖ４にドラム１３，２１および胴２０，２２が増速する間に、フィーダボード６はシート装着される。このために時点ｔ８でモータ３９が駆動され、フィーダボード６のシート装着が速度ｖ６で行われる。速度ｖ６は、時点ｔ８もしくは時点ｔ９でのドラム１３，２１もしくは胴２０，２２の速度ｖ７もしくは速度ｖ８よりも高い。第１のシート４が前当て７に達すると、時点ｔ９で、フィーダボード６のシート装着が中断される。フィーダ１におけるシート搬送が再び開始されるまで、待機時間ｔｗ３＝ｔ６−ｔ９が経過する。時点ｔ６から、フィーダ１におけるシート搬送と印刷ユニット２，３におけるシート搬送とは同期的に進行し、その際、シート４は本刷り運転で印刷される。 In the aspect shown in FIG. 2, the sheet-fed printing press includes a separate drive motor 39 for the feeder 1. Therefore, there is no mechanical drive coupling between the transmissions 30,33. Similarly to the motor 29, the motor 39 is controlled by the control device 35. With such a drive assembly, the printing units 2, 3 and the feeder 1 can be operated with mutually independent speed profiles, which is shown in detail in FIG. While the starting speed v 2 drums production rate v 4 from 13 and 21 and cylinder 20, 22 is accelerated, the feeder board 6 are sheet attached. The motor 39 is driven at time t 8 to the sheet mounting the feeder board 6 is performed at a speed v 6. The speed v 6 is higher than the speed v 7 or the speed v 8 of the drums 13 and 21 or the cylinders 20 and 22 at the time t 8 or the time t 9 . When the first sheet 4 reaches the front lays 7, at time t 9, the seat mounting of the feeder board 6 is interrupted. Until the sheet conveyance of the feeder 1 is started again, the waiting time t w3 = t 6 -t 9 has elapsed. From the time t 6, synchronously progress the sheet conveyance in the sheet conveyance and the printing units 2 in the feeder 1, in which the sheet 4 is printed in this printing operation.

シート４がフィーダボード６に搬送される速度は、シート特性に応じて調節することができる。例えば速度は、シート厚さ、剛性、表面粗さまたは摩擦係数に応じて調節することができる。例えば、シート４がフィーダボード６に搬送される速度は、薄いシート４では、厚いシート４の場合よりも遅くすることができる。分離して制御可能な、フィーダ１のための駆動装置と、印刷ユニット２，３のため駆動装置では、敏感な紙の場合に、シート４を、目下の増速速度よりも低い速度でフィーダボード６に搬送することができる。   The speed at which the sheet 4 is conveyed to the feeder board 6 can be adjusted according to the sheet characteristics. For example, the speed can be adjusted depending on the sheet thickness, stiffness, surface roughness or coefficient of friction. For example, the speed at which the sheet 4 is conveyed to the feeder board 6 can be made slower for the thin sheet 4 than for the thick sheet 4. In the case of sensitive paper, the feeder 4 for the feeder 1 and the drive unit for the feeders 1 and 3 which can be controlled separately, the sheet 4 is fed at a speed lower than the current acceleration speed. 6 can be conveyed.
